With the Alpha Theta XDJ-AN + Pioneer DJ DM-50D-BT Zwart + Pioneer DJ HDJ-X5, you can mix live for an audience. You can use the headphones to pre-cue your mix. This means you prepare your mix with transitions and effects without the audience hearing it. You hear clear sound thanks to the 40mm dome tweeter. You hear every pitch in detail thanks to the wide frequency range of 5 to 30,000Hz. The audience hears the final result through the speakers. The grooves on the speaker channels reduce air friction, so the bass sounds powerful. This way, the audience clearly hears the beat of the music. You can connect the speakers to the controller via Bluetooth or via the RCA connection. The DJ controller has 2 channels. This lets you connect 2 audio sources and mix 2 tracks at the same time. You use separate faders, effects, and equalizers for each channel, so you can create smooth transitions.
